Simple solution: This extension cable only needs to connect 4 8pin to convert it into 12+4pin, which is simple and safe to power the GPU. It is recommended to use a power supply above 1000W for better and more stable performance.
Note: Do not use PSU 8 Pin to Dual 6+2 Pin PCIE power cable as two connection ports to avoid overload power supply problems. We recommend using 4 PCIE power cables for better and more stable performance.
Stable Current Transmission: SYBECHATF PCIE 5.0 extension cable uses 16AWG tinned copper wire, compared with 18AWG cable, this can bring more stable voltage transmission and higher power output, this 4090 extension cable supports up to 600W output, if You are having a problem with insufficient red power light on your GPU, this would be a good solution.
Clean and tidy: This 4090 4080 and 3090ti special extension cable can perfectly replace the original large and thick power cord, the computer case is more beautiful, equipped with a cable comb, allowing you to easily achieve clean cable management and unified design.
Specially designed for RTX 4090/4080/3090TI: SYBECHATF 16(12+4)pin male to 4x8pin female sleeve extension cable is specially designed for GeForce RTX4090, RTX4080, RTX3090ti, the cable adopts high-density flexible protective sleeve, braided nylon fiber, length For 14 inches, this extension cable is not suitable for GPU with 12pin interface such as RTX3090, only supports 12+4pin GPU such as RTX4090, RTX4080, RTX3090ti and 4000 series.
